A scalene triangle.
an non symmetrical 4 sided shape such as a Rhombus or a Trapezoid
A nine sided POLYGON is called a nonagon. Any plain shape bounded by nine straight sides is a nonagon.
12Infinitely many all different:As it is only the area that matters, the perimeter can be any shape:An equilateral triangle (with sides approx 3.398 units)A square (with sides approx 2.236 units)A regular pentagon (with sides approx 1.705 units)A regular hexagon (with sides approx 1.387 units)A regular heptagonA regular octagonA regular nonagonA regular decagonA regular hendecagon (11 sided polygon)A regular dodecagon (12 sided polygon)A regular triskaidecagon (13 sided polygon)A regular 14 sided polygonA regular 15 sided polygonA regular 16 sided polygon...A circle (with radius approx 1.262 units)And there are also the non-regular shapes, eg an L shaped hexagon, a kite, a parallelogram which can have an area of 5 square units.
There is no maximum. For any integer n, there is a regular polygon (a 2-d shape) with n sides. And there are non-regular polygons as well.
A circle is non-polygon. Meaning it has a curved side. A circle has no sides. It is non-regular.
There is only the hexagon- regular or non regular
A scalene triangle.
There are no regular solids with an odd number of sides and therefore no regular solids with 5 faces. For this reason there is no give name, as such, for a 5 faced solid. There are however non-regular solids which have 5 faces, such as a square pyramid and a triangle cylinder.
A 9 sided shape that how many a nonagon has.
A non-descript four sided figure is a quadrilateral.
Any 5 sided shape constructed from straight non overlapping lines. A 5 sided polygon.
an non symmetrical 4 sided shape such as a Rhombus or a Trapezoid
A nine sided POLYGON is called a nonagon. Any plain shape bounded by nine straight sides is a nonagon.
You can have a 3d shape with any no of sides 3d only means there are three measure needed to calculate volume, or in other words you can pick it up and touch it. These three measurements are width, depth and height. If the faces all had to be of the same area and flat there might not be a 7 sided 3d shape (or a regular one at least) there can always be a n-sided non-irregular shape even a 1,253,703-sided irregular shape is theoretically possible.
Most non-regular quadrilaterals.
A 3-sided polygon is a triangle. There is no diagonal for that shape since all non-adjacent vertices share a line segment!
